A Reddit client for SailfishOS

Quickddit was broken so I thought I'd fix it and publish my own additions to it, as the previous maintainer seems to have abandoned it. Reddit still don't officially support third-party clients, so I'm not sure why this is still working at all, and it may well stop working soon. Maybe the userbase is just too small for them to notice.

Things I've added:

• Fixed token refresh so you can log in again now.
• Fix notification opening.
• Filter the subscribed subreddit list as you type a subreddit name.
• Use the current post title instead of just 'Comments' in the cover.
• Added URL sharing for posts and images
• Improved video stream detection and updated youtube-dl
• Fixed some broken thumbnail fetching
• Embed inline gifs and images in comments.
